The shell of this small limpet is about 6–10 mm in length and 2–3 mm in width. The shell dimensions are narrow to correspond with the limpet's habitat: the narrow blades of surfgrasses in the genus Phyllospadix, found at low tide levels. This species occurs in the Eastern Pacific Ocean, on the coast of North America, from Vancouver Island, British Columbia to northern Baja California, Mexico.[1]
These small limpets graze on the film of microscopic algae that covers the leaf blades of the marine plant Phyllospadix. As can be seen in the accompanying photos, the limpet scrapes off this algal film, leaving a clear trail on the surface of the blade behind it.
